How to fertilize Fairy Castle Cactus
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Fairy Castle Cactus after it doubles in size or once a year—whichever comes first.

Advice on what’s going on with my cactus? Is this rot? Decay? Should I cut off these stalks. The ones that are brownish are like that on one side, but the other is green. Could use some guidance! #FairyCastleCactus

Hi #FairyCastleCactus #Cactus fam! Help!My poor little guy isn’t looking so hot. One side just turned much lighter color than the other 2 and is a little squishy. I assume I overwatered. The last watering was Nov 14 and I’ve been watering a small amount every 2-3 weeks. It has a grow light. Can the damaged portion be saved?

What the heck could this be? Should I be worried, or is this just one of those things that cactus does. It does not scrape off or move. I did overwater 2 weeks ago. I watered too soon. I hope she is not sick. #fairycastlecactus #cactusclique #happyplants #pestcontrol #plantsmakepeoplehappy
